Peugeot 106 MOT

[imperial21]

Hi
I am just doing some mot repairs for a friend on there 106, It failed on Nearside rear brake recording little or no effort.
I have had the drum off and checked the worst i can find is the wheel cylinder is just starting to leak, I would nt have thought that would cause a fail ? I do mean just starting to leak, there is nothing on the shoes etc the cylinder is damp and peel back the rubber a bit and fluid comes out !
Also i see they have redesigned the adjusters on the later 106 are the ratchets on them still known to fail like the early ones ?
By the way its a 4 stud wheel.

firstly is it the service brake, hand brake or both

do the cylinder pistons slide freely,

is the adjuster of the Bendix type that loose's its tinny stainless steel ratchet locking pawl,

what condition is the hand brake cable, any bulges or cracks in the outer sheath

Hi
the mot fail was written as i put above so i guess justfoot brake . handbrake cables seem fine. also unusually for a 106 the foot brake feels good. Adjusted are different to the 3 stud ones but again seem ok. that's why i am not sure ?
i have worked on lots of 106 s and Saxos but usually the pedal feels terrible when they fail.

If you're sure the shoes and adjusters are OK then perhaps the cylinder is seizing up. If there's fluid under the boot then its about ready really anyway.

I`ve had this a lot on 106/Saxo failing on rear foot brake efficiency?? when every thing appears to be OK? They always get a poor reading on the rollers. My suggestion is,as one cyl` is leaking change both with a good bleed.Give the shoes and drums a good clean and click the auto adjusters up (not too much).

My saxo has just had it's first MOT fail in it's lifetime on rear service brake. I can't find anything obvious wrong with it and the brakes are well balanced from side to side. Fronts were both reading 200 on test and Handbrake was was over 100 on both sides but, the service brake on the rears was 57.7 and 57.9 I've had the rear drums off, nothing is leaking only a small amount of dust. I've changed both rear wheel cylinders (although couldn't find much wrong with the old ones) incase it is something to do with the inbuilt valves.
This is what they looked like when I pulled the drums off. These are the original shoes and it's a 2001 car.
